Smooth-Finish Drill Bits for Wood
High-Speed Steel
Bore clean, flat bottom holes in soft wood, veneer, and laminates. The center guide point prevents the bit from wandering. Also known as Forstner bits.

High-Speed Steel Multidiameter Drill Bits
Black Oxide
Titanium Nitride (TiN)
Uncoated
Steps with progressively larger diameters let you drill a range of sizes with one bit. Also known as step drills.
Black-oxide drill bits produce less friction than uncoated drill bits.
Titanium-nitride (TiN) coated drill bits last longer and can drill at higher speeds than uncoated drill bits and black-oxide drill bits.
